bors 1999bfaa9f Auto merge of #42913 - kennytm:fix-40569-ident-without-backtrack, r=jseyfried ...

Only match a fragment specifier the if it starts with certain tokens.

When trying to match a fragment specifier, we first predict whether the current token can be matched at all. If it cannot be matched, don't bother to push the Earley item to `bb_eis`. This can fix a lot of issues which otherwise requires full backtracking (#42838).

In this PR the prediction treatment is not done for `:item`, `:stmt` and `:tt`, but it could be expanded in the future.

Fixes #24189.
Fixes #26444.
Fixes #27832.
Fixes #34030.
Fixes #35650.
Fixes #39964.
Fixes the 4th comment in #40569.
Fixes the issue blocking #40984.
